LAcING-srUD-snrriivc MACHINE.

Patented July 31, 1917.

Application filed February 13, 1915. Serial No. 8,113.

Be it known that I, EDwAnD E. VAKE- rinLD, a citizen of the UnitedStates, and i'esident of the city of Providence, in the county ofProvidence and State of Ilhode Island7 have invented certain new anduseful Iinpi'oveinents in Lacing-Stud-Setting Machines, of wliich thefollowing is a specification.

This invention relates to improvements in machines for automaticallysetting lacing studs sucli as hooks or eyelets in slioe uppers, and hasfor its object to provide means adapted to work in conjunction with sucha machine for feeding a strip of 'reinforcing tape to the shoe upper tobe connected to the upper by the setting of the lacing studs thereinto,this tape to serve as a support, reinforcement or backing for the thinupper and to prevent the studs froin pulling out. This invention is animprovement on my co-pending patent application Serial No. 845,989.

A further object of this invention is to provide means whereby the stripmay be readily severed after the required length has been connected tothe upper.

A further object of this invention is the provision of means whereby thestrip may be partially severed if desired as it is being laid on andconnected to the upper, to cause the strip to conforin more readily tothe curve of the upper without wrinkling or buckling.

It is found in practice in the attaching of lacing studs such as hooksor eyelets to the slioe upper that in the better qualities of goods, itis desirable to sever the hacking strip into a length for eachindividual stud which will cause this backing to lie flat upon thesurface of the upper while being laid in a curve to follow the naturalform of the edge of the upper without wrinkling or buckling7 themechanism for accomplishing which, is set fortli in my prior patentapplication above referred to, but in the lower grade of goods where thestock is thin and lacking in strength7 I preferably apply this backingstrip to the upper in a single length without severing the same betweenthe studs. In this way the maximum reinforcing efi'ect is obtained fromthe backing strip to strengthen the stock not only about the studsbutbetween the same when set.

Then again in applying this backing strip to the medium grade of uppers,it is sometimes found advisable to cut or notch the edge of the strip toallow or perniit it to better conform to the cui've of the upper as itis attached thereto, to avoid in a measure its wrinkling or bucklingwhen laid in a curved form.

Vith these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1- is a front elevation of the feeding head pai'tly in sectionshowing the presser foot in engageinent' with the work and thereinforcing tape as being connected to the work by a plurality of lacingstuds, and a severing blade being raised so as not to cut the strip whenthe punch descends.

Fig. 2- is a view of the mechanism illustrated in Fig. 1 showing thepunch raised after having set the last stud in the upper and the presserfoot in extreme raised position causing the knife to sever the strip.

Fig. 3- is a side elevation showing a portion of the feeding headand'the mechanism through which the presser foot is raised to cause thetape to be brought into contact with the edge of the knife and severed.

Fig. is a plan view of the presser foot showing the guide block throughwhich the tape is fed, as slidably mounted in said foot.

lFig. 5- is a f'ace view of the knife blade showing the edge set on anangle to the plane of the strip whereby it may be adjusted to partiallysever the strip between the studs when desired.

Fig. 6- is a view of the inner side of the shoe upper showing thereinforcing tape in one continuous piece all connected to the upper bythe setting of the studs.

Fig. 7- shows the reinforcing tape as connected to the shoe upper andthis tape as having been partially severed between the studs.

In the z accompanying drawings I have illustrated a hook setting machinewith my tape feeding and severing mechanism operatively connectedvthereto, but the saine is as well adapted for use on an eyelet settingmachine, as the strip serves as a reinforcement for either a hook oreyelet, and I have, therefore, adopted the term lacing stud, which isused throughout the specification and claims and is intended to inclucleboth the hook and the eyelet.

I In the accompanying drawings and specification, I have shown anddescribed only sufiicient mechanism to illustrate my present invention.

In the drawings 10 designates a portion of the carriage in which ismounted the punch spindle 11 and the presser foot spindle 12, the latterspindle being supported from the former by the collar or guide blocks 13and 14:. To this spindle 11 is connected the punch 15 which forms holesin the upper b and also in the strip of stiffened reinforcing tape 16for the reception of the lacing studs 17, the cutter blade 18 is alsoshown as being mounted in the blocks 13 and 14 to move with the punchspindle. This cutter is provided on one of its faces with rack teeth 19which are eng-aged by the pinion 20, the latter being provided with anOperating handle 21, the rotation of which causes the plate 18 to beraised and lowered relative to the spindle carrying the same. A clampingmember 22 is provided to engage the head 21 of the pinion 20 to bind andretain the same in any desired position after the knife has been set. Bythis arrangement, it will be seen that the knife blade may be adjustedvertically, whereby it may be set so as to sever the tape at eachsetting operation of the stud or itmay be raised so as not to sever thetape eXcept when the presser foot raises the tape up into contact withsaid blade or again the knife blade may have its edge formed on an angleto the plane of the strip and by this adjusting mechanism the knife maybe set to sever just the desired portion of one edge of the strip as thepunch descends to set the stud. By this means the same machine may be'adjusted to perform several classes of work. The guide block 23 isconnected to the presser foot spindle 22 and is provided with alongitudinal aperture 24 through it which serves as a guide throughwhich the strip 16 passes, and by which the strip is accurately guidedover or to the upper which it is to be laid on and connected in thedesired position tliereto.

The outer edge of this block is provided with a hardened plate 25 havingan aperture through which the tape also passes and this plate serves tocoperate with the edge 26 of the cutter 18, whereby the latter is causedto slide upon that of the former and when it is desired to have thetwocoperate the guide block 23 with its plate 25 is raised sufcientlytoward the edge of the blade to sever the strip passing therethrough.

This block 23 is mounted to slide longitu- (linally in the presser footproper 27, see Fig. 1, which presser foot is connected through the arm28, member 29 and spring pressed spindle 30 to be operated from the foottreadle 31 through the connection 32 and lever 33 pivoted at 34:,whereby when it is desired to raise the presser foot to set the work,this treadle is pressed down slightly to permit the work to be entered,adjusted or reinoved therefrom; but when it is desired to sever thestrip the presser foot is raised still further causing the two cuttermembers 25 and 26 to coperate and sever the strip which raising actionis obtained by a little further pressure of the foot upon the treadle.By this construction, it will be seen that the strip may be severed atany place desired by a simple operation of the foot treadle which raisesthe combination cutter and guide block up sufiicient to coperate withthe cutter plate.

In the operation of my improved device the tape 16 is led from a reel,not shown, through a suitable guide 35 supported from the arm 3G whichis connected to the presser foot 27, see Fig. 4-. In this guide, 1 havemounted a tension spring 37 which permits the tape to advance butprevents the same from reccding or moving backward during the returnstroke of the feeding mechanism. From this guide the tape is led throughthe aperture 21 in the guide block 23 above the engaging surface of thepresser foot and over the Cutting edge of the cutter plate 25.

ln setting the machine for the operation of applying a hacking strip tothe upper b, the end of the strip is advanced by hand beyond the cuttingedge of the block 23 beneath the punch 15. Thepunch now desrends intothe position illustrated in Fig. 1 piercing the strip and the upper andthen with a lateral motion moves both the strip and upper into the nextposition over the pocket plate 38 which latter coperates with the punchto set and rivet the studs in the upper and at the same time secures thereinforcing strip to the back thereof. The punch spindle is now raisedand inoved to the right a dietance equal to that between the studs,while the upper is held in fixed position by the presser foot. rTheoperation above described is repeated at the setting of each stud, themovement of the head to the left serving to draw out the strip and thesetting' of the studs secures the strip and the upper together. lllhenthe desired number of studs have been set into the upper and strip thehead is stopped in the advanced position. illnstrated in Fig. 2 and theoperator presses his foot upon the treadle 31 and raises the presserfoot and guide block 27 until the knife edge 26 engages and sevei's thestrip. The upper is now removed from the machine and another positionedherein and the presser foot lowered to rctain the same.

The next movement of this head in be` ginning its operation upon thefresh upper is to the right, which causes the strip to o extend thedesired distance beyond the punch, the next operation forces the punchdown through the projecting end of the strip and t-he operation ofsetting the studs in this upper is repeated in the manner abovedescribed.

By the laying of a full or unsevered strip onto the back of the upper,it Will be seen that the maximum support is obtained, that is, the stripnot only serves as a support about the stud but also serves as a supportbetween the different studs to stiffen and strengthen the uppermaterially along` its edge at the point Where greatest strain isexerted.

In some instances, I have provided a knife blade 39 having a cutting'edge 40 set at an angle to the face of the strip as illustrated in Fig.5 and When this blade is loivered by means of the rack and pinion 19 and20 its point 41 will pass through the edge of the strip 16 and partlysever the same by which arrangement I secure the effect illustrated inFig. 7, which as Will be seen pcrinits the strip to more readily conformto the curved edge of the upper Without wrinkling or buckling.

I have shown and described one form of inechanism for attaching thestrip to the upper by setting a plurality of studs therein but any meansfor performing this function Will fall Within the spirit and scope ofthis invention.
